Ndezvipi zvinhu zvichakanganisa viscosity yehydroxypropyl methylcellulose?

Nekushandiswa kwedhaka rakanyorova, hydroxypropyl methylcellulose ine yakanaka thickening zvivakwa, inogona kuwedzera zvakanyanya kugona kwekubatana pakati pevhu rakanyorova uye base layer, uye zvakare inogona kuvandudza iyo anti-sag kuita kwedhaka, saka inoshandiswa zvakanyanya mukupura Mota, yekunze. wall insulation system uye zvidhinha bonding mortar.

Nekuda kwekukora mhedzisiro ye cellulose ether, inogona zvakare kuwedzera homogeneity uye anti-kupararira kugona kwezvinhu zvitsva zvakasanganiswa simende-based, uye zvakare inogona kudzivirira matambudziko eku delamination, kupatsanura uye kubuda ropa mudhaka nekongiri. Inogona kuiswa kune Fiber-yakasimbiswa kongiri, pasi pemvura kongiri uye self-compacting kongiri.

Hydroxypropyl methylcellulose inogona kuwedzera viscous performance ye simenti-yakavakirwa zvinhu. Kuita uku kunowanzobva kune viscosity ye cellulose ether mhinduro. Kazhinji, nhamba yenhamba ye viscosity inoshandiswa kutonga viscosity ye cellulose ether solution, nepo cellulose Viscosity ye ether inowanzoreva kunyanya kusanganiswa kwe cellulose ether solution, kazhinji 2%, pane imwe tembiricha, yakadai se20 degrees uye. chiyero chekutenderera, uchishandisa chiridzwa chekuyeresa chakatarwa, senge viscometer inotenderera. Viscosity kukosha.

Viscosity ndiyo imwe yeakakosha paramita yekuongorora kushanda kwe cellulose ether. Iyo yakakwira viscosity yehydroxypropyl methylcellulose mhinduro, zviri nani kutaridzika kwesimende-based zvinhu, uye zvirinani kuita kwekunamatira kune substrate. Panguva imwecheteyo, ine The anti-sagging kugona uye anti-kupararira kugona kwakasimba, asi kana viscosity yayo yakawandisa, inokanganisa kuyerera kwekuita uye kushanda kwesimende-yakavakirwa zvinhu.

Ndezvipi zvinhu zvichakanganisa viscosity yehydroxypropyl methylcellulose? Zvikuru zvinoenderana nezvikonzero zvinotevera.

1. Iyo yakakwirira dhigirii yepolymerization ye cellulose ether yehydroxypropyl methylcellulose, iyo yakakura huremu hwayo hwemamorekuru, zvichikonzera kukwirisa viscosity yemushonga wayo une aqueous.

2. Kana huwandu kana huwandu hwe cellulose ether yakakwirira, viscosity yemhinduro yayo ine aqueous ichave yakakwirira. Zvisinei, kungwarira kunofanirwa kutorwa pakusarudza huwandu hwakakodzera hweselulosi ether paunenge uchiishandisa, kunyanya kudzivirira huwandu hwakanyanya hweselulosi ether. Ichakanganisa kushanda kwedhaka uye kongiri.

3. Kungofanana nezvinwiwa zvakawanda, viscosity ye cellulose ether solution inoderera nekuwedzera kwekushisa, uye iyo yakanyanya kuwanda kwe cellulose ether, kuderera kwekushisa. Kunyanya kukanganisa.

4. Cellulose ether solution inowanzova pseudoplastic, iyo ine maitiro ekuveura kuonda. Iyo yakakura iyo shear rate panguva yekuedzwa, iyo idiki iyo viscosity.

Kubatana kwedhaka kuchaderedzwa nekuda kwekuita kwesimba rekunze, iro rinobatsirawo pakutsvaira kuvakwa kwedhaka, zvichiita kuti pave nekubatana kwakanaka uye kushanda kwevhu panguva imwe chete. Nekudaro, kana iyo cellulose ether mhinduro ine yakanyanya kukwirisa Kana iyo viscosity yakaderera uye viscosity idiki, icharatidza maitiro eNewtonian fluid. Kana iyo yekuisa pfungwa ichiwedzera, mhinduro inozoratidza zvishoma nezvishoma maitiro epseudoplastic fluid, uye kana iyo yekumisikidza yakakwira, iyo pseudoplasticity ichave yakajeka.
